In a rental I have this bedroom window that is very strange. It is the kind that opens sideways. However, BOTH sides of the window move. As a result, I cannot figure out how to get the window to lock. Even if I were to place a wooden rod on the inside to prevent one side of the window from opening, the other side can simply be opened from the outside.

It appears that both sides of the window are in a separate groove in the window frame. Bugscreen is in its own groove but was removed for the video demonstration.
There are locks on both sides of the window but they do not work with each other. In other words, I cannot pull down the lever when the two locks meet.

Is it possible to get this window to lock or has it been installed improperly? Is this something I can do (I love DIY but no experience with windows) or should I get the landlord to take care of it? What is involved in fixing it?
I am worried since I have some valuables in the house and no way of locking the window.
Thank you.
